Adult William's Syndrome: The Cause of an Unusual Vasculopathy and Biliary Abnormalities

A man in his 50s was diagnosed with William’s syndrome (WS) following the investigation of severe vasculopathy and bile duct abnormalities. The vascular lesions included: right carotid artery hypoplasia, tortuous dilated left carotid artery, severe aortic hypoplasia, and pulmonary branch arterial stenoses. The bile ducts were dilated with damaged and inflamed intrahepatic ducts. The patient had been labeled with fetal alcohol syndrome as a consequence of his mother’s alcohol addiction. The etiology is thought to be the combined effects and his genetic condition and prenatal alcohol exposure.
